However, the name of the Nomen associated with this king is not clear. To confuse the issue further, the name Weneg is written with a rather obscure flower glyph (translated as "wng") which Grdseloff suggests was mistakenly replaced by the papyrus-plant glyph (Wadj) early in Egyptian history, changing his name to wadjnes (e.g. in the Abydos kings list). This resulted in Manetho mistranslating the name as "outgot-las", which he shortened to "Tlas".

Weneg is sometimes linked to Raneb, the second ruler of the dynasty. Jochem Kahl suggests that a badly damaged fragment (shown) found in the tomb of Sekhemhib (Seth Peribsen) depicts the weneg flower beside elements of Raneb's name and beneath the inscribed name of Ninetjer. He proposes that the weneg flower was connected to Raneb's name, and Nynetjer later usurped the inscription.

Other Egyptologists (notably Nicolas Grimal, Wolfgang Helck and Walter Bryan Emery) propose that Weneg was Sekhemib-Perenmaat who they considered to be a distinct ruler (as opposed to being one and the samen as Sekhemhib (Seth Peribsen). This theory is not widely accepted, because clay seals of Sekhemib were found in the tomb of Khasekhemwy (the last ruler of the second dynasty) suggest that Sekemib reigned towards the end of the dynasty while Ramesside references to "Wadjenes" place this ruler near the beginning of the dynasty.

Some scholars suggest that in fact "Weneg" was the same person as Sendji, although both are listed in the Abydos kings list so this would seem less likely.

Finally, some have proposed (e.g. Peter Kaplony and Richard Weill, and Toby Wilkinson) that he was an entirely distinct king who ruled after Nynetjer. The length of his reign is uncertain, and the fact that he is unattested outside of Saqqara may suggest that he only ruled over an area of lower (northern) Egypt. Helck suggests he may have used the Horus name Sa (or Za), although other scholars link this name with either Nubnefer or Senedj.

It is interesting to note that Weneg is also the name of a god referred to in the Pyramid Texts. He supported the sky and was the judge of the other gods (as an aspect of the sun god, Ra).
